IMPRGVEIVIENT IN EYELETlNG-MACHINES.

Specification forming part of Letters Patent No. 'AQG, dated August 21, 1866.

To all whom it may concern:

Beit known that I, GEORGE SHIPMAN, of West Bridgewater, in the county ot' Plymouth and State ot' Massachusetts, have made a new and useful Invention having reference to Machinery for Inserting and Fixing Eyelets in 4(Jloth or other Sheet Material; and I do hereby declare the same to be fully described in the following specification, and represented in the accompanying drawings, of which- Figure 1 is a top view, and Fior. 2 a side elevation, of an eyeleting-inachine provided with 1n yinvention. Fig. 3 is a section. taken through the eyelet-magazine and the chute leading therefrom.

My invention is principally for the purpose of supporting the eyelet-magazine and operating it, its brush, and the punch by which the eyelets are upset.

In the drawings, A denotes the supporting frame or standard of the machine, it being formed in manner and so as to project from a base-plate, B, as represented.

O is the punch, which carries a pin or eyelet receiver, a., supported by a spring in the usual manner, the same being as shown in Fig. et, which is a vertical section of the punch, its pin, and the elevating-spring b thereof. The punch should be so applied to the standard A as to be capable of sliding vertically therein and toward and away from a stationary upsetter, I), formed and arranged as represented in Figs. 2 and 3. At its lower end the'punch is connected with one arm of a lever, E, by link-connections, whereby, by lthe movements of the lever on its fulcrum c, vertical and longitudinal motions will be imparted to the punch. The said lever, arranged against the standard A, as represented, has, with another lever, F, a common t'ulcrum, c, projecting from suchstandard; and, furthermore, a cylindrical pin or stud, d, extending from the lever E, enters a round hole, c, made in the shorter arm fot' the lever F, such hole having a diameter larger than that of the stud d.

lFrom the front arm ofthe lever E an ear, g, extends, and has a screw or adjustable stop, It, screwed down through it, the ear being provided with a set-screw, i, to be screwed up against the stop in order to prevent it from revolving when properlyy adjusted, so as to determine the extent of depression of the punch, which it will do by contact with the base-plate B. Another such ear, k, and stop Z are applied to the other arm of the lever E, the same being to limit the upward motion ot' the punch. There is also another such ear, m., and stop oz applied to the longer arm of the lever F, they being arranged in manner as represented in Fig. 2. In this latter case the stop is to determine the extent of advance of the eyelet-chute, and this it does by contact with anear, o, projectin g from the standard A.

The eyelet-magazine G, with its chute H, is supported by and fixed to the longer arm of the leverF, the whole being arranged as shown in Figs. l and 2. This eyelet-magazine is a cylindrical box containing a reciprocating brush, l', arranged radially within the box and applied to it so as to move concentrically within it.

The spindle m of the brush has a crank, u', projecting from it, and connected by a rod, o', with a stud, p, extended from the standard A. A series of ports, r r o', is made through the circumference of the magazine, and so as to open into the chute, each ot' such ports having a form corresponding with or analogous to a section of an eyelet made in line of its axis.

During the backward and forward movements of the magazine and the chute the brush will be moved within the magazine so as to torce more or less ot' the eyelets through the ports and into the chute, down which they will pass, with their smaller ends upward, until they are estopped by a lever or gate, s, applied to one side of the chute and so as to project in front of its open end. rThe said gate, formed as represented in the drawings, turns on afulcrum, t, and has a spring, infor forcing its rear arm away from the chute.

An arm, c, extending from the standard A, not only serves as a guide or support for the longer arm of the lever F, but to sustain a spring, w, which extends from it down to the rear arm ofthe lever E, such spring being for the purpose ot' moving such lever in one direction after it may have been moved in the opposite direction by a foot-treadle when connected with it.

the front arm of such lever will be elevated a short. distance, so as to cause the pin of the` punch to pass up into an eyelet at the end of the chute and against the gate, the lever F being at rest in the meanwhile. A continuance of the movement ot' the lever E will produce such a movement of the lever F on its fulcrum as Will cause it to move both the eyelet-magazine'and its chute in a direction away' from the pin of the punch and the eyeleton such pin. The lever E will also at the same time effect the elevation of the punch, so as to cause it to move the eyelet upward toward the upsetter D' and into the hole ot' the cloth or material destined to receive it, such cloth or material being supported on a furcated rest, I, applied to the standard A, and arranged as shown in Figs. l and 2.

During the upward movement of theeyelet the punch will force the pin a against the conic frustum 3/ of the upsetter, and such eyelet Will be forced upon the said part y and up against the shoulder e of the upsetter, so as to be upset thereby, or be turned down upon the cloth.

After this may have taken place the lever E will be moved in an opposite direction by `the spring w, and Will so move the lever F. as to cause it to move the magazine and its chute forward. This movement of the magazine will cause the brush thereof to force the mass of eyelets across the ports, whereby some of the eyelets Will be ejected through the port-s and into the chute. v

A guard, K, xed to the periphery of the magazine by screws a a', and arranged over the curved part of the chute, serves to prevent the escaping eyelets from being ejected from the chute by the momentum imparted to them by the brush.

I make no claim to any invention described in the specifications ofNos. 1,729 and 1,730 of reissues of United States Patents.

What I claim as my invention isl. The application and arrangement of the two levers E F together and to the standard A, the eyelet-punch, the magazine, and chute, substantially as and for actuating such magazine and chute, substantially as described.

2. The application and arrangement of the spring a with the standard A and the two levers E F, appliedtogether and to such standard, and the punch, magazine, and chute, substantially as specified.

3. The combination as Well as the arrangement of the three adjustable stops h Z u with the levers E F, when arranged and applied together and to the frame of the machine, the punch, the magazine, and its chute substantially in manner'as speciiied.

' 4. The combination and arrangement of the elastic buffer w with tbe standard A, the lever F, and the magazine and chute applied to such lever.

5. The combination and arrangement of the adjustable guard K with the eyelet-magazine and its ports, the chute, and rotary brush, arranged together, as specified.
